So close I can feel the PowerTap!

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

I'm about two weeks away from having a new PowerTap Pro in my hands so I can start putting into practice training by power and all the good tips I've found in the multitude of power posts I've been reading. One final question...

Since, I'm purchasing by internet, do I need to worry about them shipping me an older version? Have there been any significant changes or fixes to flaws in the PowerTap Pro since it came out? If there have been changes or upgrades, what has changed and how can I tell which version one I'm getting?

Hoping to have more to contribute to this forum in the near future.

Cheers!
